Lea Valley lines

The Lea Valley lines are two commuter lines and two branches in north-east London, so named because they run along the Lower Lea Valley of the River Lea. They were part of the Great Eastern Railway, now part of the Anglia Route of Network Rail.

On 31 May 2015, services between London Liverpool Street to Chingford, Cheshunt and Enfield Town were transferred to London Overground; services between London Liverpool Street and Stratford via Tottenham Hale to Hertford East and Bishops Stortford remain with Greater Anglia.
